Neil Muller https://2016.za.pycon.org/talks/20/ Python CFFI (C Foreign Function Interface) provides a powerful set of tools for interacting with C from Python. In this tutorial, I will cover the basics of using CFFI, including the various modes it can be used in. I will also cover several of the more advanced aspects, such as callbacks, and describe the mechanisms for distributing modules that use Python CFFI.
